There is much uncertainty regarding the sources of reactive mercury (RM) compounds and atmospheric chemistry driving their formation. This work focused on assessing potential measured in Reno, Nevada, United States, using 1 year data collected Reactive Mercury Active System. In addition, ancillary meteorology criteria air pollutant data, Hybrid Single-Particle Lagrangian Integrated Trajectory (...

شرایط افروزش و اشتعال سوخت‌های گداخت هسته‌ای در حضور ناخالص­‌ها، یکی از موارد مهمی است که طراحی قرص‌های سوخت باید مورد توجه قرار گیرد. این مقاله اثر ناخالصی هسته سنگین طلا بر کلیه فرایندهای احتراق پلاسمای غیرتعادلی دوتریم- تریتیم مدل چهار دمایی آن شکل تابع توزیع انرژی رفتار فوتون‌ها تأثیر می‌گذارد بررسی گرفته است. مطالعه شامل اثرات منفی سوخت، طول زمان تشکیل لکه داغ نتایج محاسبات عددی به­ دست آم...

Deterioration of air quality due to the increase in atmospheric emissions from biomass burning (BB) is one major environmental problems worldwide. In this study, we estimated contributions BB PM 2.5 concentrations municipalities Soledad and Malambo located Colombian Caribbean. The evaluation period ranged February 24 March 30, 2018, a with high number events recorded surroundings evaluated site...

Abstract A series of meteorological measurements with a small uncrewed aircraft system (sUAS) was collected at Oliver Springs Airport in Tennessee. The sUAS provides unique observing capable obtaining vertical profiles data within the lowest few hundred meters boundary layer. benefit simulated plume predictions by providing more accurate to dispersion model. can be used directly drive HYSPLIT s...

Research on the spatial flow of ecosystem services can help to identify the spatial relationships between service-providing areas (SPAs) and service-benefitting areas (SBAs). In this study, we used the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model to stimulate the flow paths of the wind erosion prevented by ecosystems in Hunshandake, China. By interpolating these paths...

This contribution evaluates an approach using an extended Kalman filter (EKF) to estimate the planetary boundary layer height (PBLH) from lidar measurements obtained in the framework of the European Aerosol Research LIdar NETwork (EARLINET) at 12 UTC ± 30-min for a 7-year period (2007-2013) under different synoptic flows over the complex geographical area of Barcelona, Spain. PBLH diagnosed wit...

This study focuses on analyzing the changes to aerosol properties caused by the dust storm called “China’s Great Wall of Dust” that originated from the Taklimakan Desert in April 2014. IDDI (Infrared Difference Dust Index) images from FY-2E and true color composite images from FY-3C MERSI (Medium Resolution Spectral Imager) show the breakout and transport path of the dust storm. Three-hourly gr...
